Ever heard of Bymotorveien (1965) in Oslo?

This plan included a 16-lane motorway through downtown Oslo, and would require demolishing about 12 whole city districts.

Such extreme urban motorway plans weren't unheard of in the 1960s.
London, for example was supposed to get 4 (!) motorways ring roads, that would have required the demolition of large areas of the city.
In NYC they planned several elevated freeways across Manhattan.

It is good to distinguish four different things: a vision, a scenario, a plan, and the implementation.

Everyone can draw lines on a map, but these seldom are serious plans but basis for the further discussion.

Similar maps were drawn in Helsinki, too:



Later generations have said this was a plan, but it is not true. The City of Helsinki ordered four different scenarios based on various assumptions, and this was one of those.

Two quite violent motorway implementations took place in Finland in the 1960's, in Hämeenlinna and Karhula:





In addition, there were a plan to destroy the city of Jyväskylä:



The first 2 kilometers of that plan got built. The times changed quickly, and the plan was abandoned. Later, the motorway section has been downgraded to a street.

I raised the question because I did not know there are arrangements like the Sandesund brigde of Sarpsborg in Norway. (Not counting anything in Oslo, were such constructions are understandable.) I have driven on this bridge, but one cannot see the motorway bridge details while driving on it.

Fv. 7 Bjørga Tunnel

The 1.6 kilometer long Bjørga Tunnel in Granvin municipality opened to traffic today. It bypasses a stretch that is prone to rockslides. It also bypasses a scenic, but very narrow stretch of road.

Does anyone know when it's expected to be opened, early, mid or late 2017?

Fv. 653 Eiksund Tunnel

I visited the northwest coastal region of Southern Norway in June. I took a ride across County Road (fylkesvei) 653 from Volda to Eiksund.

Fv. 653 runs through the Eiksund Tunnel. It is 7.7 kilometers long and goes 287 meters below sea level. It's the deepest undersea tunnel in the world. There is an 8% grade on average, maxing out at 9.6%. There is also an average speed check, even in 2nd gear you have to brake to keep it from going over 80 km/h. There are climbing lanes uphill on either side.

The real altitude difference is closer to 350 meters as the tunnel portals are located higher than sea level.

1. Coming from Volda, along the Ørstafjord.

2. Average speed check sign.

3. The Eiksund Tunnel.

4. The Eiksund side of the tunnel-bridge.

5. The surrounding mountains are between 900 and 1300 m high.

6. The Eiksund Bridge

7. Panoramic view. It was a great and warm day (the average high in Volda is only 13°C in June).

Most of the stretch opens january 2017. Electronic works delays opening of the tunnels with 2-4 months. So in may 2017 everything should be ready.

The only other example I can think of is the E18 crossing in Drammen (https://en.wikipedia.org/wiki/Drammen_Bridge). Incidentially, this is also a 1km+ crossing built in the 1970s and dualled in the 2000s.

Oslofjord Crossing

Statens Vegvesen has recommended to build the northern bridge route to cross the Oslofjord south of Oslo.

The current Oslofjord Tunnel (7.3 km, 7% grade) opened to traffic in 2000. The tolls were lifted in 2016.

Earlier studies included southern alternatives. Present studies have focused on northern alternatives.

There were a couple of alternatives considered;

* build a second tube to the existing tunnel
* build a new tunnel route to the north (11 or 14 km long)
* build a new bridge route to the north

The northern routes allow for a motorway-standard road, with 110 km/h with the bridge alternative and 90 km/h with the tunnel alternative.

Twinning of the existing tunnel was eliminated due to the steepness, safety and the fact that a northern route shortens travel distance by 7 kilometers. The northern tunnel alternatives were eliminated based on safety, maintenance and availability.

So Statens Vegvesen has recommended the northern bridge route.

There are still two alternatives;

* a box girder bridge (west bridge) and suspension bridge (east bridge)
* double-span suspension bridge (west bridge) and suspension bridge (east bridge).

If the latter is chosen, it would be the first major double-span suspension bridge in Europe. The spans would be in the range of 2 x 700 - 750 m for the west bridge and 1000 - 1100 m for the east bridge.

Really hope they end up with alternative 6. But alternative 2 with a suspension bridge in west is also fine.

Alternative 6 includes alternative 2 (both suspension bridges). It just has different routes on each side.

Political support for the E134 via Haukeli and the Bergen Arm, Bergen-Odda is growing. The Conservative party in Hordaland supports the Bergen Arm, a true political breakthrough. The Conservatives were the only opponents for the Bergen Arm. There was already a political majority to support Rv52 as second EW road and the construction of the Bergen Arm.



http://www.bedrevei.no/
There are signals KVU for the Bergen Arm to E134 Haukeli-Oslo will be implemented in the first half of next National Transport period, that means before 2025. When we assume a construction time of 3 years for the new Jondal bridge, a ferry–free and short road from Bergen to Oslo may be available in 2028.

Why this route wasn't chosen 20 years ago when it's such a shortcut is incredible.... The tunnel could maybe be used for indoor downhill skiing in the future? Such a facility have been proposed for numerous locations around Oslo.

Could it have something to do with the planned airport at Hurum? Statens vegvesen recommended a bridge over a tunnel in the 90s too, but further south than the current proposal. The decision to build the tunnel was political after vocal local protests to the bridge plans.

Here's a render of the bridge the alternatives considered in the early 90s:

Ljø Tunnel

The 3650 meter long Ljø Tunnel will be inaugurated on 17 December. The tunnel is part of Fylkesvei (County Road) 60 between Hellesylt and Stranda (near the Geirangerfjord). It bypasses two older tunnels.

A lot of infrastructure built or planned in the 1990s seems to have been planned with the lowest cost in mind. They're already expanding or replacing roads and tunnels built 20 years ago...

Just recently I've read about a proposal to bypass the entire Gudvanga Tunnel and Flenja Tunnel on E16. And they're also reconsidering tunnels with a steep grade, which are now seen as unfavorable and unsafe. Steep tunnels account for a disproportional large amount of tunnel fires.

Only 4% of the tunnels have a grade of 6% or more, but 44% of the tunnel fires occurs in them. And they're more likely to be low-volume tunnels, which suggests these steep tunnels are significantly less safe than tunnels with grades of 5% or less. They also changed the grade on the Boknafjord Tunnel relatively late in the planning process (making it longer).

E6 Tana Bridge

Today a 333 million NOK contract was signed to construct the new Tana Bridge (E6) in Northern Norway. It will be completed by fall 2019.

It is a cable-stayed bridge with a total length of 260 m, of which the main bridge is 224 m long and the main span is 180 meter long. The pylon will be 95.2 meters tall.

The current bridge is only 5 meters wide and was built in 1948. It is the only bridge across the Tana River in Norway, and thus the only road access to eastern Finnmark. The nearest bridge is near Utsjoki, some 70 kilometers upstream on the Finland border.

The shortest route between eastern Finnmark and most of Norway is through Finland (and Sweden) anyway

To clarify: The bridge is the only road access to eastern Finnmark on the Norwegian road network. There are roads via Nuorgam and Sevettijärvi in Finland as well as the E105 via Russia.
